VULCANIZING APPARATUS.

Application l'ed January 7,

To all whom it may concern:

Bc it -known that I, J AMES W. ARTHUR, a citizen of the United States, residing at Akron, Ohio, have invented certainnew and 6 useful Improvements in Vulcanizing Apparatus, of which the following.is a specification.

My present invention relates to improvements in vul-canizers desig1ied-iiiore especially for the repair of inner tubes of pneumatic tires.

One object of the invention is to provide a self contained unit which can,be easily iiioY-ed about whilein operation to any desired place' in the work room or garage.

Another object is to provide a construction capable of operating upon a plurality of tubes, all of which will be so disposed as to be free from Contact with the lameor :0 any. heated part, other than the part being vulcanized.

, A further object is to provide a convenient means for storing the fuel supply, and to generally simplify the construction.

With these and other objects in view the invention includes thenovel features of construction and-arrangement and combination of parts hereinafter described and particularly defined by the appended claims.

An embodiment of my invention is illustrated in the accompanying drawing, in which, J Y Figure 1 is a side elevation of my proved vulcanizing apparatus.

Fig. 2 is a front view thereof, and, Figs. 3 and 4 are detail views.. *Fig 5 is a view of a modification.

Referring by reference characters to this drawing the numeral 1 designates an elon- 40 gated vulcanizing plate which has a d ownwardly facing vulcanizing face of suitable. width and ofa length capable of accommodating simultaneously a plurality of tubes, the apparatus shown in the drawings being 46 designed tn handle four, as a' convenient y number. The back or upper part of the vulcanizing plate is formed as a steam chamber l to which steam is supplied in the manner hereinafter described to secure the necessary 60 vulc nizing heat.

T e plate is supported by a standard 2rY which is supported at its lower end by legs 2 and 2" provided with casters or similar means enablin the vul'canizer to be readily `155` moved from p ace to place.

Specification of Letters Patent.

1919. serial No. 270,028.

The standard is made hollow and closed at its lower end and is'adapted to serve as a reservoir for liquid fuel, being provided at its upper end with a filling opening 2 preferably of funnel shape, and having a shut off cock c.

A' boiler 3 for gencratingsteani and carrying a gage glass 3 is secured to the standard by suitable means. such for example as the clamp 4 and beneath the bottom of the boiler is a liquid fuel burner 5 of the ordi nary or any desired type which is connected by a pipe 6' with the interior of the fuel reservoir at .the bottom thereof. T he top of the boiler is connected b a pipe 7 with the steam space 1a above referred to.

The fuel is forced to the burner b v air pressure which is supplied by a hand pump 8 connected with the standard or pedestal above the surface of the liquid fuel contained therein. f

The tubes to be repaired are intended to be pressed against the under or vulcaiiizing face of the plate 1 and to accomplish this in an expeditious and effective lmanner I provide a plurality of bell cilank levershaving arms 9 projecting beneath the vulcaniziiig plate and carryingr presser plates 10 designed to support the looped portion of the tube and to press the patch or part to be vulcanized upward against the heatedplate. The blocks are rovided with downwardly extendingV spaced) lugs 10a adapted to straddle the arms 9 and therebydiiold Ythe blocks removably and adjiistably ii position, each block being capable of being slid along the corresponding supporting/arm 9 to any dcsii'ed position. The bell crank levers 9 are fulcrumed on bearing brackets 11 carried b v or formedintegial with the table or plate 1 and the arms 9 of the bell crank levers are connected by tension springs 1-2 to a cross bar 13 supported by uprights 11 from the ends of the plate 1.

' The springs tend to draw the arms 5 3 uri- Wardly and hence hold the arms J and black.` 10 pressed againstthe under face of die Avulcanizing plate iwith the tube clamped therebetween.

Means may be provided for adjusting the llll u tension of the springs such as the sci-ey: rods 15 threaded through the bar 13 and their loiver ends `provided With a having sivive connection with the springs. Each arm 9 is connected by a rod i6 with a no Upon release of the treadle lever the tube will be pressed upward against the vul-` canizing plate and it will be sure that the portions of the tube not subjected to vuloanizing action hang free from and out of Contact with any heated part and clear of the flame of the burner.

Instead of using springs to secure the clamping effect I may use counter weights, as shown in Fig. 5, lin which event the overlying frame 13 is dispensed with the bell crank arms are extended substantially horizontally rearward, as indicated at 9b and carry weights 12b which tend to throw the arms 9 carrying the presser pads or blocks upwardly in the same manner as do the springs of the form previously described. The weights are made adjustable on the arms 9b to vary the pressure and may be locked in adjusted position by set screws 12C.

In this modification I have shown how the air to the fuel tank may be supplied from a pipe line 8a instead of a pump carried by the apparatus.

Having thus described my invention, what 1 claim is 1. A vulcanizing apparatus comprising a vulcanizing plate having a downwardly facing horizontal surface, a pivoted arm extending substantially horizontally beneath the same, means normally pressing said arm toward the plate, means for swinging the arm away from the plate and a pressure pad having a forked part straddling said arm, and held thereto by fric- `tional contact only, said pressure-pat being slidable horizontally on said arm.

:2. A vuleanizing apparatus comprising a hollow standard forming a fuel reservoir, a boiler supported by said standard, a fuel burner connected with said reservoir to receive fuel therefrom, and a vulcanizing member supported by said standard having a steam space connected with said boiler.

A vulcanizng apparatus comprising a vulcanizing member having a downuardh7 facing horizontal surface, a bell crank lever pivoted at one side thereof and having substantially horizontal arms lying respectively aboveand below said membena pressure pad carried on the underlying arm, a spring exerting tension on the overlying arm, means for adjusting the tension of the spring and a treadle lever connected to the underlying arm.

l. A vulcanizing apparatus comprising a hollow standard forming a fuel reservoir, a boiler supported by said standard, a fuel burner connected with said reservoir, means for forcing compressed air into said stand ard` and a vulcanizing member supported by said standard having a steam space con nected to said boiler.

5. A vulcanizing apparatus comprising a hollow standard forming a fuel reservoir,

and feet at the lowerend of said standard a carrying wheels orcasters.

(i. A vulcanizing apparatus comprising a hollow standard forming r fuel reservoir, supporting legs diverging from the lower end of said standard, a boiler supported by said standard. a burner below the boiler connected with said reservoir, a pump for forcing air into said standard, a horizontal vulcanizing member carried at the upper end of said standard. spring pressed arms coacting with said vulcanizing member, a rod or shaft supported by two of said legs, treadle levers pivoted to said rod, and means connecting said arms with said treadle levers. v

In testimony whereof, I aflix my signature.
